In this image you see the solding of the lead terminations, which makes the connection on the printed circuit board for this small toroidal transformer. This transformer was for a medical application.
Each individual part is tested. In this image the soldered toroidal transformers are tested to see if they meet the client’s specifications. All data is saved for later use.
We are using a small hook winding machine, specifically used when the core is extra small. This machine winds directly around the core itself creating a toroidal transformer or inductor.
